GPO n Mode

The GPO n mode feature configures the operational mode of the camera's general-purpose output (GPO) pins, where "n" denotes a specific pin number. This configuration allows you to set the GPO pins for various signaling purposes, such as indicating camera status or synchronizing with external devices.

Available modes include:

• Exposure: Outputs a pulse that is active during the camera's exposure time.
• Readout: Outputs a pulse that is active during the readout period.
• GPO: Functions as a general-purpose output, with the state set by the pin's polarity.
• Test Generator: Generates a frame time clock with a variable duty cycle. See trigger frame time and trigger high time for more information.
• Strobe: When used with a trigger delay, this mode outputs a pulse you can use to warm up lighting before exposure starts. This pulse:
  • starts when an input pulse on GPI_n starts, and
  • ends when the input pulse ends plus the length of the trigger delay time, if any.

GPO_n_Mode node

• Access mode: Read/Write
• Node type: Enumeration

You can use the eSDK API functions to:

• get and set the node’s current value, and
• get the node’s value options.
